between the adjacent edges.
Porcelain enamel panels, in addition to their use in the walls of bathrooms, kitchens, and other interior locations, are bein used more and more on exterior walls where they are exposed to the weather, including driving rains. The joints between the panels are filled with mortar or a mastic compound as a caulking to provide a watertight construction. It is difficult, if not impossible, to insure that the joints will be permanently watertight and will not permit water to leak through into the interior portion of the wall where it will cause considerable damage. The watertightness of these joints is dependent on the quality and characteristics of the caulking compound and even though it be of good quality, poor workmanship in its application often results in leaky joints despite the fact that the joints are successfully sealed in the original installation. The life of the caulkin compounds, so far developed, is much shorter than the life of the porcelain enamel panels so that the building develops leaks in a relatively short time and requires frequent and continuing maintenance. Caulking such a large number of joints even in a small building is a relatively costly and slow process. Another important difliculty involved in the use of caulking compounds is that any movement of the porcelain enamel panels due to temperature changes, settlement of the building or other causes, tends to destroy the Watertightness of the mortar-filled joints and causes spalling of the enamel because the panels are rigidly fastened to the building structure. Attempts have been made to provide weatherproof walls without the use of a caulkin compound in the joints, but these attempts have not, in general, met with success. One reason for thislack of success is that there is nothing preventing the rain from driving through the seam and into the interior of the wall.
It is an object of this invention to provide an improved interlocking panel which is economical to manufacture and which may be readily assembled with other, like panels to form a weathertight wall without the use of a caulkin compound in the joints between the panels.
A further object of this invention is to provide a novel wall including porcelain enamel panels that will have a life determined by the relatively 2 long life of the porcelain enamel coating and not by the relatively short life of the caulkin compound that has heretofore been used.
It is also an object of this invention to provide a new and useful watertight wall with drainage channels in back of the seams between the adjacent panel edges which will prevent the en trance of any water into the interior portion of the wall where it may cause damage. a I
Another object of the present invention is to provide means for fastening the panels together which will normally hold the panels against movement but which will tend to center the panels if erected slightly off center and which will permit slight floating movement of the panels when settling of the building, temperature changes or other causes tend to shift the panels so as to prevent or reduce spalling of the enamel.
The present invention provides a new and novel interlocking panel and these panels may be readily assembled into a novel Waterproof wall without a caulking compound in the seams between the adjacent edges of the panels. The wall comprises a plurality of panels assembled with their closely adjacent edges forming non-watertight, aligned seams therebetween. Relatively large expansion and drainage channels are provided in back of the horizontally and vertically aligned seams. These channels reduce the velocity of any water driven through the seams into the channels and since the velocity of the entering water is immediately reduced, the water will not be driven beyond the limits of the channels and the channels will drain away the water driven through the seams and into the channels. The panels are fastened to the supporting means by resilient elements which hold the panels against normal movement but permit some floating movement of the panels when there is a tendency for the panels to shift which may be caused by temperature changes, settling of the building or other causes. My novel panel is economical to produce and may be readily erected at low cost to form an improved wall.
While this invention is primarily concerned with porcelain enamel panels normally comprising a piece of sheet metal decorated with a porcelain enamel coating, it is not limited to such materials. The panels may be formed of any other suitable material such as opaque, translucent or transparent plastics or glass, molded wood products, and the like, having the necessary weathering properties and decorative surfaces. While I am primarily concerned with vertical walls, my invention is not limited to such walls and, may be used for ceilings, roofs and other horizontal or inclined walls.
These and other objects and advantages will become more apparent from the following detailed description and the accompanying drawings, in which:

Figure 4 is a front elevational view of a portion of the supporting channel of Figures 1 and 3;
Figure 5 is a fragmentary sectional view taken along line 5-5 of Figure 1;
Figure 6 is a fragmentary'sectional viewtaken along line 66 of Figure 1'; and,
Figure 7 is an isometric view of the clip also shown in Figure 3 for fastening the panel in place.
Referring to the drawings, the wall shown in Figure 1 comprises a plurality of panels I fastened to and supported by the vertical channels or studs II as will be more fully herinafter described in detail. The channels I I may be formed of relatively light weight sheet steel or other material where they support only the weight of the panels It or may be formed of relatively heavy material when supporting part or all of the weight of the building. The adjacent edges of the panels are shown as being spaced apart a very slight distance suiflcient to prevent damage to the porcelain or other decorative coating along the edges when the panels are being assembled, but the edges may be in contact with each other. In either arrangement, the panels are assembled with their adjacent edges forming aligned, vertical, non-watertight seams I2 and aligned, horizontal, non-watertight seams I3 therebetween.
The hollow, pan-shaped panel Ii] is formed by forming a thin sheet of steel to which the porcelain coating is then applied. Each panel In comprises a front wall I4 which may be flat, as shown, or which may be embossed, stamped or otherwise deformed, coated or treated to present the desired decorative efiect. The edges of panel wall M are preferably slightly rounded as it is possible to more evenly enamel a round corner as compared to a sharp corner. An inwardly turned flange I extends along each of the two opposite, end edges of wall I4 and an inwardly depressed channel portion I6 extends across the upper edge of the front wall I l. The upper end portion of each flange is deformed to form a continuation of channel portion IS. The channel shaped portion I6 includes an inwardly bent, horizontal bottom shoulder IT, a web I8 parallel to wall I4, and asubstantially perpendicular outer flange l9 extending along the edge of web I8. The shoulder [1, web IB andflange I9 define a U-shaped channel with its open side toward the front of the panel. Near each end of the channel portion I6, there is formed a recess 21 and the flange I9 is lanced adjacent each end at 20 and opposite the recess 2i for the reasons more fully hereinafter described. An inwardly directed flange 22 extends across the bottom edge of the wall I4 and terminates in a downwardly bent lip 23.
A hook-shaped clip'25 is fastened to the-web I8 by rivets 24 and extends along the channel substantially as shown in Figures 3 and 5. The clip includes tabs 26 which are bent back to receive and hold the lip 23 of an adjacent, upper panel Ill. Other means may be used for fastening the clip 25 in place.
Channels II are supported in horizontally spaced apart positions-as indicated in Figure 1, and each drain channel includes a back web 21 having an outwardly bent flange 28 extending along each vertical side so that the web 2'! and channels 28 define a U-shaped channel passage with its open side toward the panels. Each flange 28 is provided with a notch 29 for each supported panel I9; At the bottom of notch 29 there is an inwardly extending, horizontal tab 30 and at the back of notch 29 there is a vertical, inwardly bent flange portion 3 I. A second relatively small inwardly bent tab 32 is provided at the upper side of notch 29.
When erecting a wall, the channels II are first properly positioned. The bottom panels are first fastened in place and then the next higher panels and so on, similar to the sequence used in fastening shingles in place. A lower panel is first placed in position with the end flanges I5, each in-a corresponding channel II, and then pressed into place so that the depressed channel shaped portion It fits into the corresponding pair of notches 29. The recessed portion 21 contacts the inwardly bent flangev portion 3|, as shown more clearly in Figures-6 and '7, and the shoulder I! of channel portion I6 rests on the tab 3%} at the bottom of notch 29. Thus, the weight of each panel i8 is supported by two flanges-28. The panel'is removably fastened to the channel II by a spring clip including two leg portions 35, each terminating in a hook portion 36. The spring clip 33 is placed in position so that its straight portion 3& extends across the top of flange I9 and the upper edge of flange ill with one leg 35 in back of flange portion 3| so that its hook portion 36 engages the upper end of flange I5 at and with the other leg 35 fitting the lancedportion 2!! of flange I9 so that its hook portion 36 engages the end of flange I9. The inwardly bent tab 32 holds the clip 33 in position. The clip-33 urges the web I5 away from flange SI and is normally compressed so that, as shown in Figure 3, the clip tends to urge the panel toward the right. The two opposed clips 33 thus tend to center the panel I0 with respect to the channels II. Each spring 33 resiliently urges each panel I8 toward the center of the adjacent, corresponding channel II, urges each panel I8 inwardly against flange portion 3I, and urges each panel downwardly toward the clip 25 in the channel portion I6 of the adjacent lower panel. The springs 33 can bereadily removed to permit'dismantling of the panels.
As shown more clearly in Figure 6, the flange 31 normally. does not quite touch the flange I5 of the next adjacent upper panel. The flange portion .3I does not contact the. back of the upper portion of flange I5 and the flanges I5 of two horizontally adjacent panels do not touch. Thus, each panel can shift horizontally a slight amount, that is, the panel has some. horizontal float. If there is atemperature change or settling of the building or any other causes tending to slightly shift or move the panels, this floating movement is sufficient to permit the panels to move and prevent or greatly-reduce spalling 0f the porcelain coating. The clips 33 are normally strong enough to prevent movementv of .the panels by windor by rial and form a seal.
hand. At times, when erecting a wall, the panels may not be positioned in perfect vertical alignment and the clips 33 will tend, over a period of time, to center the panels with respect to the previously described.
Insulating material may, if desirable, be added to the back of each panel front wall it. Enough clearance must be left so that the panels can be assembled. The flange i9 is slightly nared outwardly and if there is insulating material on the back of the adjacent upper panel, the resilient flange [9 will press against the insulating mate- The springs 33 holding each panel in place urge the panel downwardly against clip 25 and if insulating material is present, they urge the insulation against resilient flange 19.
Referring more particularly to Figure 5, the U-shaped channel portion it defines a velocity- -reduoing passage or channel 38 which is in back vofand above the seam i3. When, for example,
a driving rain strikes the panels, water is driven through horizontal seam l3 into the channel 35. The cross sectional area of channel 38 is much greater than that of scam 83 so that the water entering the channel from the seam has its velocity reduced and it immediately drops to the bottom of channel 38 and drains into the vertical drain channel H. Because of the reduction in velocity and the relatively large size of the channel 38 as compared to seam it, the water does not tend to push between the edge of flange I9 and wall It at 39 and enter the building structure where it will cause considerable damage.
As shown more clearly in Figure 6, the seam l2 opens into the velocity-reducing channel or passage defined by studs l i so that any water driven through seam l2 enters this vertical drain channel where its velocity is greatly reduced so that it immediately drains to the bottom of the channel. As the horizontal drain channels 33 communicate with the vertical drain channels defined by the studs H. all of the water entering the seams l2 and it eventually flows out of the bottom of channels ii to the ground or other locations where it will do no harm. If the channels H and panels Iii are assembled to form, for example, a roof, the lower ends of the channels may be directly above the eaves trough so that water draining from the channels ll will flow into these troughs and be drained away in the usual manner.
The panels Hi can be very rapidly and easily assembled once the channels ll are in place for it is only necessary to place each panel in position and snap two wire clips 33 into position. The assembled panels and channels provide a weatherproof Wall Without the use of a caulking compound and the wall is so constructed that the life of the wall is not limited to the life of the caulking compound and the panels are so supported that there is little or no tendency for the porcelain enamel coating to spall off under ,a change of temperature or settling of the building.
